Create MR backlog entries from reacted messages for triage

When merge requests are flagged in a busy channel, reviewers lose context and items go untriaged. This captures flagged MRs into a backlog for triage and assignment, enabling same-day review.

Overview

Flagged merge requests in chat often never make it into a triage backlog, leaving reviews delayed and releases at risk. This workflow captures those flagged messages as tracked records so engineering managers and release coordinators can triage and assign changes for same-day review.
